This pull request updates the ImageKit Editor to version 1.2.0 and introduces several UI improvements to the editor's header and wrapper components. The main focus is on enhancing the appearance and consistency of the header buttons and layout, as well as ensuring the correct z-index stacking for the editor wrapper.

UI Improvements in Header:

• Adjusted header layout by adding paddingRight="0", removing gap="4", and adding mr="4" to the icon for improved spacing and alignment.

Editor Wrapper Styling:

Using a magic number (2100) for z-index instead of a named constant or theme token reduces maintainability. Consider defining this value as a constant (e.g., EDITOR_WRAPPER_Z_INDEX = 2100) or documenting why this specific value is necessary, especially since it replaces a semantic theme token 'modal'.
